Fuels | Investigation of viscosity, density and cloud point of diesel and biodiesel blends

Besides kinematic viscosity and density according to ASTM D7042 and D4052, SVM 3001 Cold Properties also simultaneously determines the cloud point of diesel fuel thanks to its built-in optical cell.

Legislation and the importance of sustainability necessitate more investigation into fuels for our everyday needs. This results in an increased focus on renewable resources.

Diesel fuels both from petroleum and renewable sources and blends thereof need to fulfill a number of criteria, including

  • Kinematic viscosity at 40 °C
  • Density at 15 °C
  • Kinematic viscosity at -20 °C for winter diesel used in cold and arctic climate areas
  • Cold flow properties: Cloud Point (CP) / Cold Filter Plugging Point (CFPP) / Low Temperature Flow Test (LFTF)

in order to satisfy various specifications as defined by ASTM D975, ASTM D6751, ASTM D7467, EN 590, EN 14214, EN 16734, EN 16709 and others. SVM 3001 Cold Properties provides kinematic viscosity, density and the cloud point in one go as a scan. Measuring kinematic viscosity at -20 °C does not require external counter cooling equipment.
